The blue tungsten oxide furnace, also called turning tube furnace, is a must device in the powder metallurgy industry (especially the metallurgy of tungsten and molybdenum), whose main use is to turn the semifinished product apt (ammonium paratungstate) into blue tungsten oxide and molybdenum through the proper control of temperature, time, inside atmosphere and pressure in furnace. The pif-regulated control system, for the temperature control, consists of the thermal coupler, temperature controller and controllable silicon trigger and features its evenness and precision of control. The staying time of furnace materials can be set by changing the rotation speed and slant of the furnace tube on the basis of the process requirements. The gases in the furnace chamber can be customized as hydrogen, ammonia or air.

1200â?? tube furnace uses high-quality electric furnace wire as heating element, the maximum heating temperature is 1200â??, and the diameter of the quartz furnace tube is 50mm. If the customer needs, can contact the technician to customize the larger diameter furnace tube. The default heating zone is single temperature zone. It can also be customized according to customer needs. The temperature zone is controlled by the precision temperature control meter for PID temperature control. The 30-segment temperature rise and fall program can be edited, and the overheating and open circuit of thermocouple protection functions are also available. The flanges on both sides of the furnace tube are equipped with a digital vacuum gauge and a mechanical pressure gauge, which can be used to control the atmosphere in the furnace tube. At the same time, the tube furnace is operated by HD true color touch screen, which is easy to use. Even non-professionals can master the use of the instrument after simple training, which can greatly improve your experiment efficiency. 1200â?? tube furnace application rangeï¼? Tube furnaces are mainly used in metallurgy, glass, heat treatment, lithium battery positive and negative materials, new energy, abrasives and other industries, and can also be used for heat treatment in atmospheric environment. It can also be used to form a CVD system for related coating test production.

The glass is mainly made of silica sand and soda ash as raw materials which are melted at a high temperature. Glass melting furnaces are thermal equipment for melting glass and are usually constructed of refractory materials. Glass melting furnaces can be divided into two categories: pool kiln and crucible kiln. The pool kiln is the most commonly used kiln type in the glass industry. It is made of refractory materials, and has a flame pool kiln and an electric kiln. Casting zirconium corundum bricks are commonly known as white iron bricks. It is the most important refractory material to ensure the normal operation of the glass melting furnace. At present, the melting rate of the glass melting furnace at home and abroad is increased, the kiln age is extended, and the fuel consumption is reduced mainly due to the use of the refractory material. The use of fused zirconium corundum brick in the glass melting furnace is to build the upper pool wall, small furnace flat raft, small furnace raft, stone raft and chest wall.
